A 9.00 is actually 40.5Understood, it just seems like an unnecessary risk to me.
As far as the measurements, my understanding is that 9.00 or 11.00 is generally referred to as the sidewall height of the tire. These tires are assumed to have a 100% aspect ratio, so it also happens to be the width.
A 9.00 x 20 tire would be 38 inches tall. An 11.00 x 20 would be 42 inches, so it would be a 4 inch difference.
Here is a pretty good link that explains military tire sizes pretty well.
